Sports Predictions is extremely powerful, flexible and easy to manage from the backend. I've been running prediction leagues on my site with many users and it works effortlessly. All you have to do is set up your teams, leagues and upcoming games, then assign the games to the appropriate league(s). Users have options to enter score prediction or margin predictions.
The standings views update instantly when result is entered in backend. Standings have almost unlimited filtering and sorting options to determine how you want your winner to be found and how you want the standings to be displayed to users simply by manipulating the URL query string.
The new primary scoring options test for accuracy over quantity which means your users don't fall way behind if they miss some games so their interest stays peaked to continue playing and not drop out. In addition, users can view personal statistical history with a chart to visualize performance by week, day and year. You will find several other goodies packed in this component.
The best part is the guys at 3D Web Design are extremely helpful and forward thinking so expect even more great additions to be included in future versions.
